1.
Reliable mechanical seals, used in a long period will not leak or rarely known.Clean, no dead
Angle, can prevent bacterial contamination.
2. Service life is long,
the correct selection of friction load pressure mechanical seal can use 2 ~ 5 years, the longest
useful to 9 years.
3. Maintenance cycle is
long, in the case of normal work, don't need to repair pump seal.
4. The shaft or the shaft
sleeve is not subject to wear and tear.
5. The friction power loss
is little, generally is about 10 to 50% of the gland seal
6. The precision of the
mechanical seal on the shaft and the finish is not so strict, packing requirements
of pendulum axis and axis is not sensitive to the shell hole deflection,
sensitivity to the vibration of the shaft.
7. Applicability is wide and can be used in
low temperature, high temperature, high vacuum and high pressure, speed, and
corrosive, abrasive, inflammable, explosive, toxic medium sealing.
